What is the difference between axial, centrifugal, forward, backward, belt driven, in-line fans?
For several application you need different kind of products, the following table shows you what kind of fans exist and in which field they are used:

Kind Adjustment Advantage Applications
Axial air maintains parallel movement within the fan   Provides a better air-movements in ventilation systems
Axial in line Motor set in line with the propeller Simple design Use for clean air
Axial belt driven Motor is set outside the housing, using of a belt Motor has no contact with the airflow Can be used for polluted air
Centrifugal air maintains perpendicular movement in relation to the fan Used for a transportation of air, generates an high airflow  
Centrifugal forward Movement and design of the propellers is forward Higher air flow available Used for short transportation ways
Centrifugal backward Movement and design of the propellers is backward Higher static pressure available Used for longer transportation ways  enabled because of the higher static pressure
 Ventilator    Enables a good air exchange
